These days many git repos are changing their default branch from “master” to “main”. I’m 99.9% sure that this won’t affect plugin manager builds since we specify branch and commit-sha for the build already. True?
When I submit an update to the plugin manager, I identify only a commit hash.
As far as I can tell, the plugin manager neither knows nor cares about branches, default or otherwise.
No problems from my side…
You can call your branches whatever you like:
release, etc. and it won’t affect VCV Library builds because as @dhemery says, submodule commits are specified by commit hashes, not branch names.
